Email marketing consistently delivers a better ROI than any other marketing channel. Plus, it's brilliant for community building and engaging with your customers on what feels like a one-on-one level. But if you don't have the right infrastructure in place to handle your email marketing, you're not going to be able to reach your subscribers and customers in the way you need to encourage engagement, build those important relationships, generate more leads, and increase sales. That's why we've put together this list of the top email marketing platforms on the market right now. Each of the email marketing platforms on this list offers a unique set of features to explore so you can find the perfect email marketing platform to get the results you need.

Before we dive into our list, we're going to take a little time to answer some questions you may have about email marketing, why it matters, what an email marketing platform actually is, and the features you should look for. 

19 of the Best Email Marketing Software Platforms for 2021:

Why Does Email Marketing Matter?

As we've already mentioned, email marketing has one of the best ROI of any marketing channel. Despite the fact that email marketing has been around for decades, it still earns an ROI of 4200%—for every $1 you spend on email marketing, you have the potential to earn back $42 in return. Some reports even put email marketing ROI closer to 54%! When you consider that about 4 billion people around the world use email (Statista), this isn't a surprise. With such a large audience spread across different demographics, it would be shocking if email marketing didn't have a great ROI. ROI aside, email marketing helps you reach more customers and subscribers, increase your sales, and improve brand recognition.

No matter your industry, email marketing will help you get your marketing message out to the right people and gives you a way to stay connected with your target audience after they've left your website. Here are a few more reasons why your brand should be using email marketing:

  • Loyalty. Email gives you the chance to get website visitors back to your site again and again. And people who come back to your website are more likely to become customers than those visiting your site for the first time.
  • Returning visitors. About 97% of the people who visit and leave your website will never come back. That's a sobering statistic for most online businesses. However, by building an email list, you can encourage repeat visitors (and increase our first bullet point, loyalty).
  • Increased revenue. Email marketing gets excellent conversion rates. Barilliance reports that the average conversion rates for email marketing in 2020 were 15.11%. Plus, purchases resulting from email marketing campaigns tend to be larger.

What's an Email Marketing Platform?

Now that you're convinced email marketing is worth it, you're probably wondering what an email marketing platform actually is and why using one matters. An email marketing platform is a software that lets you create and manage your email marketing campaigns. Simple enough, right?

Email marketing platforms are typically SaaS (Software as a Service) tools that are cloud-based. A high-quality email marketing platform makes it easy for you to send out any email communication, from email newsletters to promotional emails to abandoned cart recovery emails.

What Should Email Marketing Platforms Do?

Your email marketing platform should ultimately make your life easier, helping you automate your emails and marketing campaigns and making it easy to create beautiful and engaging emails to send to your customers and subscribers. We recommend looking for these six features when choosing the best email marketing platform for your brand:

User Interface

Email marketing platforms are supposed to make the life of an email marketer easier. Look for an email marketing platform that has an easy-to-use interface with a low learning curve to ensure that you're able to utilize all the features you need quickly and easily. A drag-and-drop email editor is a wonderful feature to have. And, if you have email designers, you'll want to choose a platform that allows for HTML email templates. If you don't have people to design your emails, make sure that the email marketing platform you choose has a collection of templates you can customize to create emails that showcase your brand.


Email segmentation dramatically increases the ROI of your email campaigns. You can create targeted marketing campaigns and promotional emails for the specific audiences that will be most interested in them based on demographics, location, behavior, and more. Some email marketing platforms even operate on AI and machine learning so the software can evaluate user behavior in real-time and fine-tune your email campaigns on the fly.


Segmentation is important if you want to personalize your email marketing campaigns. And you definitely want to personalize your email marketing campaigns. Find an email marketing platform that includes merge tags to make it easy to personalize your email subject lines as well as the email copy. There are even some email marketing platforms that use dynamic content so you can create and send a single email that automatically includes certain content depending on the segment the email is being sent to.


Email marketing has a lot of moving parts, many of which are manual, repetitive tasks. Fortunately, many of the best email marketing platforms include automation features that can help you save tons of time. Email automation includes things like email scheduling, delivery receipts, engagement tracking, text analytics, role-based account access for your marketing team, and even intelligent segmentation/re-segmentation based on response to your email marketing campaigns.


One of the most important steps to take to ensure that your email marketing campaigns are getting the best ROI is testing. Many of the top email marketing platforms include A/B and split testing functionality that lets you test different elements of your marketing emails against one another to ensure that you have the best possible combination of subject lines, copy, calls to action, email design, and format.

Reports and Analytics

There are several email marketing benchmarks you'll want to track to ensure that your email marketing is meeting your goals. However, tracking this information manually can be a full-time job. Choose an email marketing platform that includes reporting and analytics so you can track open rates, click-through rates, bounce rates, and more.
